Thunderstorms cause 5th delay for space shuttle

Thunderstorms once again forced NASA to call off the launch of space shuttle Endeavour on Monday, the fifth delay for the space station construction mission. NASA said it would try the launch again early Wednesday evening, after a one-day break. In a scene nearly identical to Sunday, launch managers halted the countdown just minutes before Endeavour and seven astronauts were supposed to blast off in the early evening.
